MOTOR BOAT AND PBOPELLING HEARS THEREFOR.

Application filed August 19, 1925. Serial No. 51,148.

This invention relates, generally, to improvements in motor-propelled boats; and, the resent invention has reference, more particularly, to the provision of a boat with 6 a gasolene-driven engine, preferably of the Ford type, combining with the general arrangement of the motor within the boat, a novel ooolin system for coolin the engine; and, furt ermore, by means the coolmg system also cooling the oil used in the casing of the engine.

The invention, therefore, has for its principal objects to provide a motor-boat operated preferably, from a Ford motor; and,

furthermore, to rovide a novel and simply constructed cooling system for cooling the engine, as well as the oil used, by taking from a point outside of'the boat a continuous supply of normally cold water, and discharging the water at another point outside of the boat, after the cooling operation has 7 been erformed.

Oti ier objects of the present invention not at this time more particularly enumerated will be more fully understood from the following detailed description of the present invention.

With the various objects of the present invention in view, the invention consists, primarily in the novel motor-driven boat hereinafter more fully set forth; and, the invention consists, furthermore, in the general arran ements and combinations of the various dev1ces and parts, as well as in the details of the construction of the said parts, all of which willbe more fully described in the followin specification, and then finally embodie in the clauses of the claims, which are appended to and which form an essential part of the said s ification.

The invention is illustrated in the accompanying drawings in which:-

Figure 1 is a side view of a boat driven in the manner of the resent invention, showing in connection with the hull or body of the boat, the intake and and the discharge end of the piping used with the water cooling system.

Figures 2 and 3 are longitudinal vertical sections of the bow-end of the boat, illustrating in connection therewith and in elevation, the reverse sides of a motor and a cooling system embodying the principles of the invention.

Figure 4 is a longitudinal vertical section of one of the cooling members of the system, said section being taken on line 44 in Figure 3; Figure 5 is a view, partly in elevation and partly in longitudinal vertical section, of a water-cooled mufiler; and Figure 6 is a transverse vertical section of the same, said section being taken on line 6-6 in said Figure 5.

Figure 7 is a detail view, showing diagrammatically, the inlet-portion of a carburetor, a portion of the feed-pipe leading to said inlet-portion, and a portion of the overflow pipe or trap connected with said feedpipe; and Fi re 8 is a detail sectional representation o a certain portion of the device, being represented as taken on line 8-8 in Fi ure 3.

imilar characters of reference are employed in all of the said above described views to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference-character 1 indicates the hull or body of a suitably-shaped boat formed with a suitable compartment,

Suitably disposed in the forward portion of this com artment is a gasolene motor or engine pre erably of the Ford type, of whjch 3 represents the usual engine-casmg The reference-character 4 indicates the main shaft of the motor or engine, said shaft havingsuitably mounted thereon a ulley-wheel 5 over which is passed a driving Belt 7. Suitably mounted upon a portion 8 of the casin 3 isz-a bracket 9 to whlch is suitably secured a p mp 10 of any desired construction, the p p-shaft of which is indicated by the refere ice-character 11. Mounted upon this shaft 11 is a pulle -wheel 12, which is adapted to be operate from the driving belt 7, as will be evident. Connected with'the inlet 13 of said pump 10 is a sup ly ipe 14, which extends through the hull or y of the boat for takin in water from outsideof the boat and delivering it into-the pump, when the latter is set in motion. Connected with the exit or deliveryrtion 15 of the pump 10 is a pipe 16 whic leads to and is connected with a suitable water-jacket or casing 17. Referring to Figure 4 of the drawings, it will be seen that this waterjacket or casing is provided with leak-proof or water-tight ends 18 and 19, and has an outlet 20 suitably located in its side. Connected with this outlet 20 is a conveyor-pipe 21 which leads to and is connected with anthe gear-mechanism, so as to propel the boat inlet 22 with which the water jacketed casing} is provided.

rom the. above descri tion it will be evident, that I have provided a simple as well as an efiicientl operating cooling system for co'ntinuou y cooling the motor or engine with the normally cold water, taken in at'the bow and discharged at the stern of the boat, the arrangement and construction ofthe cooling system also being such, that the circulating water may be used for cooling the mufier and the exhaust gases discharged into the same, thereby minimizing any hack-fire, and consequent danger of fire.

Referring now to Figure 3 of the drawings, it wiil be seen that the lubricating oil, which circulates from the transmissionportion 47 of the casing 3, through said casing and back to the transmission may be suitably cooled.

This is accomplished by connection with the portion 47, as at 48, of a pipe 49, which pipe leads into andfrom; the water-jacket or casing 17, as indicated in Figure 4 of the drawings, and which ipe 49 is connected with a suitably placed and suitably constructed oil-screemn' appliance, as 50, said device being provi ed with an outlet 51 which is connected with the casing 3, as at 52, and communicates with the. interior of sand enginecasing.

In orde'r'that the oil from the transmission may readil pass into the pipe 49, a suitably shape scoop or deflector 53, see Eigure 8', may be suitably located within {the transmission casing-portion 47, onto which the oil is splashed so as to readily flow into the pipe 48, as will be evident. i'

Forward and rearward propulsion ofi the boat is produced by the mechanism illus trated in Figure 3 of the drawings, in which'the reference-characters 65 and 66 indicate the actuating shafts of the gear-shift mechanism, enclosed in the engine-casing 3 in the usual manner. As indicated inisaid F1gure-3, the said casing is made with an extension 67, provided with a bearing in which is mounted a pintle 68. Suitably secured upon said pintle in fixed angular relation to each other is a lever 69 and a pa r of upwardly extending actuating memers, as 70 and 71. Suitab y connected with the shaft 65 is a crank 72, with the free end-portion of which is ivotally connected a link-member 73 which is also pivotally connected with the member 74'of the lever 69. Similarly mounted upon the shaft 66 in a forward or rearward direction will be fully understood from an inspection of said Figure 3 of the drawings. The referencecharacter- 77 indicates the usual speed-control means or auxilerator, which is suitably actuated from the cam-portion 78 of the member 71, as the lever 69 is moved back and forth. 7

From the foregoing description of the present invention, it will be evident, thatl have produced a simple arrangement of devices which enables the adaptation of the Ford engine to a motor ooat.

.l am aware, also, tint changes y be made in the general arrangements and comhinations of the various devices and parts, as well as in the details of the construction of the said parts, without departing from the scope of the present invention as set forth in the foregoing specification, and as defined in the clauses oi the claimsvwhich are appended thereto. Hence, 1 do not t my present invention to the exact arran ements and combinations of the various evices and parts as described in the said specification, nor do lconfirie myself tothe exact details of the'construction of the said parts, as illustrated in the accompanying drawings.
